{{more citations needed|date=January 2021}} The '''near–far problem''' or '''hearability problem''' is the effect of a strong signal from a near signal source in making it hard for a receiver to hear a weaker signal from a further source due to [[adjacent-channel interference]], [[co-channel interference]], [[distortion]], [[capture effect]], [[dynamic range]] limitation, or the like. Such a situation is common in wireless communication systems, in particular [[CDMA]]. In some [[Radio jamming|signal jamming]] techniques, the near–far problem is exploited to disrupt ("[[Radio jamming|jam]]") communications.
